Initial characterization of a prototype target–moderator–reflector assembly for an electron-driven compact accelerator-driven neutron source at CERN's CLEAR facility

This article presents the design, installation and first experimental testing of a novel prototype target–moderator–reflector assembly for a compact accelerator-driven neutron source driven by a 35 MeV electron beam.

EQSANS-CLI: a natural-language agent-ready command-line tool for small-angle neutron scattering data reduction at EQ-SANS

EQSANS-CLI is a command-line tool for small-angle neutron scattering data reduction. It exposes the full reduction pipeline through two input surfaces, an interactive terminal that accepts both slash commands and natural language, and a headless JSON mode designed for external AI agents, both built on a shared command-handler layer.

Angle-dependent X-ray absorption correction in small- and wide-angle X-ray scattering: accounting for constrained scattering volume, beam profiles and capillary wall attenuation

We present an improved numerical angle-dependent absorption correction procedure for line-collimated small- and wide-angle X-ray scattering measurements in thin-walled quartz capillaries. The procedure accounts for the constrained illuminated volume, measured primary beam profiles and capillary-wall absorption, enabling physically consistent data reduction and reliable absolute scaling when conventional experimental scalar transmission corrections become unreliable.

Influence of solidification history and particle size on defect evolution in Al2024 alloy additive manufacturing powder

Findings are presented on the impact of particle size and solidification history on defect formation in Al2024 alloy additive manufacturing powder. The results of this investigation suggest a trend of decreasing dislocation density in as-atomized samples as the particle size increases, with larger particles cooling more slowly.

Anisotropic extension of the Parratt formalism

We derive a generalized Parratt method applicable to anisotropic systems, which is devoid of the numerical instabilities arising in the method of characteristic matrices. We derive formulae for both reflectivity and transmissivity.
